System for detecting forces exerted onto a tire

A device with at least two sensors, especially tire sidewall torsion (SWT) sensors for a motor vehicle control system, wherein the sensors are mounted at varying distances from the tire rotational axis on the chassis or wheel suspension in a stationary manner and wherein the sensors interact with at least one encoder mounted on or in the tire wall or with at least one conventional encoder mounted on or in the tire wall and exhibiting poles. The output signals or output information of the sensors are transmitted to the motor vehicle control system after having been evaluated. In order to provide preprocessed or conditioned data records to the signal processing (DSP=digital signal processor), so that the signal processing software needs to carry out fewer calculating operations to correct the errors in the raw data and determine the tire or wheel forces on the basis of the conditioned data, at least one analog and one digital signal conditioning or processing unit is provided between the motor vehicle control system and the sensors.
